Detailed Description

In order to make the objects, technical solutions and advantages of the present disclosure more apparent, the present disclosure will be described in further detail with reference to the accompanying drawings, and it is to be understood that the described embodiments are only a part of the embodiments of the present disclosure, but not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed in the present disclosure without making any creative effort, shall fall within the protection scope of the present disclosure.

The application scenario described in the embodiment of the present disclosure is for more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation to the technical solution provided in the embodiment of the present disclosure, and as a person having ordinary skill in the art will appreciate, with the occurrence of a new application scenario, the technical solution provided in the embodiment of the present disclosure is also applicable to similar technical problems. In the description of the present disclosure, the term "plurality" means two or more unless otherwise specified.

At present, 135-165-inch spliced products begin to appear on indoor LED display products, and with the technical progress, infrared touch frames begin to be arranged to realize the functions of touch, video conferences and the like. However, during the use process, especially when the pen is operated or written at a close distance, the highlight of the pen easily causes visual fatigue and is very dazzling. The LED display has high brightness, can be spliced at will in size, is very suitable for large meeting places and large meeting rooms, and is very clear and bright when being watched for a long distance. At present, more and more LED splicing products are matched with an infrared touch frame to realize writing and touch functions, integrate accessories such as a camera, a microphone and a screen transmitter and are applied to meeting scenes. And the problem of edge joint of liquid crystal products is solved on the oversize.

After the LED splicing complete machine is installed, the brightness of the LED display screen has two adjusting modes. Firstly, manual setting, namely setting display brightness through system software; and secondly, an ambient light detection sensor is installed on the whole machine, and the LED display brightness is adjusted according to the ambient brightness. The two methods are conventional brightness adjustment methods, and the adjusted brightness is set to be L0, namely the brightness value which is suitable for the current use environment and is viewed in a long distance. This value may be around 500-600nit per current industry product L0. Because the LED is highlighted, the touch control, writing and other operations need to be completed by a user in a close range, and the damage to human eyes is large.

In order to solve the technical problem, the embodiment provides a more intelligent brightness adjustment method, so that when a person operates in a close range, the brightness of an operation area of a user can be lower than the brightness of other areas, the display brightness of the close range operation user using an LED screen is intelligently reduced, and the user experience is improved.

In some examples, the present embodiments provide a smart interactive tablet, which includes but is not limited to LED tiled products, LCD products, and has the characteristics of large size and high brightness. As shown in fig. 1, the display device includes a display screen 100, a touch component 101, and a driving circuit 102, wherein:

the display screen 100 is used for displaying content;

the touch component 101 is used for receiving a touch operation instruction;

the driving circuit 102 comprises a processor 103 and a memory 104, the memory 104 is used for storing programs executable by the processor 103, and the processor 103 is used for reading the programs in the memory 104 and executing the following steps:

step 1) determining a first area and a second area of a display area of the display screen, wherein the positions of the first area and the second area are not overlapped, the first area comprises at least part of the content of the display area, the first area is configured to receive a touch operation instruction of a user, and the positions of the first area and the second area are not overlapped;

and step 2) controlling the display brightness of the first area to be lower than that of the second area.

In the embodiment, a display area of the display screen is divided into two areas, namely a first area and a second area, wherein the first area is configured to receive a touch operation instruction of a user, that is, the first area is an area where the user performs a short-distance operation, and the second area can be configured as an area for displaying, so that the user can conveniently watch the touch operation instruction at a long distance. In some examples, the second area may also be configured as an area for receiving touch operation instructions, or the second area may be configured as an area for display and an area for receiving touch operations. This embodiment is not limited to a large number of embodiments. The display brightness of the first region is controlled to be lower than that of the second region, the display brightness of the first region operated by a user operating the intelligent interactive tablet in a close range is reduced and is lower than that of the second region, the first region is a region operated by the user, the second region is a region watched by a remote user, the brightness of the first region is lower than that of the second region, the use experience of the user using the intelligent interactive tablet in a close range is improved while the user watching in a remote range is not influenced, visual fatigue caused by high brightness of the intelligent interactive tablet is avoided, and the use experience of the user is improved.

It should be noted that the first area and the second area divided in this embodiment are only an example of software-based area division or an example of algorithmically divided area, that is, the area of the display screen is divided algorithmically or softly by using the processor of the smart interactive tablet, and the first area and the second area are distinguished by a plurality of forms such as an area frame, an area block, a boundary, and the like on the area displayed in the full-screen display screen, but the display screen does not have the above area division in hardware.

In some examples, the content displayed by the first region includes at least a portion of the content in the display region.

In some examples, as shown in fig. 2, the second area 202 in the present embodiment is a remaining area of the display area 200 except for the first area 201; alternatively, as shown in fig. 3, the second area 302 in this embodiment is a partial area of the remaining area of the display area 300 except for the first area 301, where the second area does not overlap with the first area. In some examples, the shapes of the first region and the second region in this embodiment may be the same or different, and the shapes of the first region and the second region are not limited too much in this embodiment. In some examples, the display area may be divided equally into a preset number of divided areas, for example, the display area is divided into four divided areas, as shown in fig. 4A, including four

areas

400a, 401a, 402a, and 403a, wherein the first area is located in one of the four areas, and the second area is located in any one of the other three areas except the first area. In some examples, the display area may be further divided into a field-shaped area, as shown in fig. 4B, including four areas 400B, 401B, 402B, and 403B, wherein the first area is located in one of the four areas, and the second area is located in any one of the three areas except the first area. The positional relationship between the first region and the second region in this embodiment includes, but is not limited to, diagonal, adjacent, and axisymmetric, which is not limited to this embodiment.

In some examples, the content displayed by at least a part of the first area of the display area in this embodiment includes the content of the second area, that is, the content of the first area in this embodiment includes the content of the second area, optionally, the content displayed by the first area includes a thumbnail of the second area, or the content displayed by the first area includes a background of the second area, or the content displayed by the first area includes core content of the second area, such as some key icons, text, images, and the like; or the content displayed by the first area comprises part or all of the content after the background of the second area is removed. In the implementation, the content of the second area which needs to be displayed in the first area is determined according to the user requirement, and the content of the second area is copied to the first area for display. Because the first area is configured as the operation area of the user, the content in the second area can be displayed in the first area, so that when the user uses a large screen for operation, the user only needs to operate in the operation area (the first area), and the use experience of the user is improved. The content of the second area may be copied to the first area for display by zooming or panning, for example, an icon of the second area is zoomed and then copied to the first area for display, or the content of the second area without a background is zoomed and then copied to the first area for display, or all the content of the second area is zoomed and then copied to the first area for display.

The partial content of the display area in the present embodiment includes, but is not limited to: the background of the display area, the icon of the display area, the document of the display area, the picture of the display area and the like. The partial content of the display area also comprises partial or whole content in the second area and partial or whole content in other areas except the first area and the second area.

In some examples, if a first area includes an icon of a second area, the present embodiment may receive a touch operation instruction of the icon of the first area; and converting the touch operation instruction of the icon in the first area into a touch operation instruction for controlling the icon in the second area. Optionally, displaying the first icon in the second area; displaying a second icon associated with the first icon in a first area; receiving a first touch operation instruction of the first area to the second icon; and converting a first touch operation instruction of the first area to the second icon into a second touch operation instruction of the second area to the first icon. In implementation, when the first area contains the content of the second area, for example, the icon of the second area is displayed in the first area, the user can operate the displayed icon of the second area in the first area, and because the current display screen has a large screen size, the touch interaction of the user is inconvenient.

In some examples, the first touch operation instruction and the second touch operation instruction are used to distinguish between performing a touch operation on the second icon in the first area and performing a touch operation on the first icon in the second area, and in essence, both the first touch operation instruction and the second touch operation instruction conform to the definition of the touch operation instruction in this embodiment. Optionally, the first touch operation instruction for the second icon includes but is not limited to: clicking an icon operating instruction, opening the icon operating instruction, starting the icon operating instruction and deleting the icon operating instruction. The second touch operation instruction includes but is not limited to: clicking an icon operating instruction, opening the icon operating instruction, starting the icon operating instruction and deleting the icon operating instruction. It should be noted that the first touch operation instruction and the second touch operation instruction are corresponding, and in implementation, a user only needs to execute the first touch operation instruction on the second icon in the first area, and correspondingly, the processor of the intelligent interactive tablet in this embodiment converts the first touch operation instruction into the second touch operation instruction on the first icon, so that the first touch operation instruction on the second icon in this embodiment is equivalent to the second touch operation instruction on the first icon, for example, when the second icon in the first area is clicked, the click operation is correspondingly converted into the click operation on the first icon in the second area.

In some examples, a first icon displayed in the second area and a second icon associated with the first icon displayed in the first area may be the same or different in shape; the names of the two icons can be the same or different; the first icon and the second icon in this embodiment may be the same or different; the second icon may be located in the same or different location in the first area than the first icon. The first icon and the second icon in this embodiment have an association relationship, and the shape, name, color, position, and the like of the first icon and the second icon having an association relationship are not limited too much in this embodiment. As shown in fig. 5A-5D, the present embodiment illustrates various ways of displaying a second icon associated with a first icon in a first area. Fig. 5A shows that only a part of the icons in the second area are displayed in the first area, and the names corresponding to the icons are not displayed. FIG. 5B illustrates all of the icons in the second area being processed in the first area, with each icon having a changed shape; fig. 5B shows that all icons in the second area are displayed at corresponding positions in the first area, where icon 1 corresponds to an album, icon 2 corresponds to music, icon 3 corresponds to a calendar, icon 4 corresponds to a setting, icon 5 corresponds to an application store, icon 6 corresponds to security maintenance, icon 7 corresponds to a writing tool, and icon 8 corresponds to weather. FIG. 5C shows that all icons of the second area are scaled and displayed in the first area, and the icon names and the background of the second area are not displayed; fig. 5D shows displaying the background of the second area in the first area. It should be noted that, the manner of displaying the icon in the second area in the first area in this embodiment is only an example, and the manners of displaying the icon determined based on the same inventive concept all belong to the protection scope of the present disclosure.

In some examples, after determining the first area and the second area of the display screen, the present embodiment is further configured to copy at least part of the content of the first area to the second area for display. Optionally, a writing instruction of the first area is received, and writing handwriting is generated in the first area according to the writing instruction; the writing generated by the first area is copied to the second area for display, and the writing of the first area can be copied to the second area for display. According to the embodiment, after the writing is generated in the first area, the writing is copied in the second area, and the written content is reserved.

In some examples, after at least part of the content of the first area is copied to the second area for display, the embodiment may further remove the content of the copied handwriting of the first area in the second area after determining that the writing instruction of the first area is finished. In some examples, the written instruction is determined to end by any one or any number of the following: determining that writing is completed, determining to wait for a preset time after writing is completed, determining to close or delete the first area, and determining to receive a termination instruction triggered by a user.

In some examples, the present embodiment determines the first region by any one of:

according to the human eye visibility of about 124 degrees, about one fifth when focusing attention, namely 25 degrees, the monocular comfortable visual field is 60 degrees, which can be preliminarily set, and when the user is at a distance S from the screen, the area where the user is more sensitive to vision is the 30-degree area around the central axis of the visual field. The radius of field of view a = S/√ 3 can be calculated, and the first region is a circle with the radius of field of view a.

It should be noted that the modes 1 c) -1 b) and the modes 1 a) -1 b) in this embodiment belong to two parallel schemes for determining the first area, where the modes 1 a) -1 b) are used to describe the modes for determining the first area according to different touch operation instructions, and the modes 1 c) -1 b) are used to describe the modes for specifically determining the first area according to the touch operation instructions, and the two parallel schemes can be implemented in combination.

Mode 2) if the control instruction is an instruction for representing that the position of the human body is detected, determining the first area according to the position of the human body and the distance between the position of the human body and the intelligent interaction tablet.

Mode 3) if the control command is a command except for the touch operation command and the command representing the detected human body position, determining the first area according to the predefined position.

In some examples, the display brightness of the first region in the present embodiment decreases as the distance between the human body position and the smart interactive tablet becomes smaller. Optionally, a multi-level dimming scheme may be set in this embodiment, and as the human body is closer to the smart interactive tablet, the display brightness of the first area is controlled to decrease step by step. In some examples, the step-down scheme provided by the present embodiment is as follows:

if the distance between the human body position and the intelligent interaction panel is larger than an operation threshold value and smaller than a viewing threshold value, determining the display brightness of the first area to be primary brightness, wherein the operation threshold value is smaller than the viewing threshold value; and if the distance between the human body position and the intelligent interaction panel is smaller than or equal to an operation threshold value, controlling the display brightness of the first area to be lower than the first-level brightness. In implementation, when the user is in a click operation state, the display brightness of the first area may be reduced, and when the user is in a writing operation, the display brightness of the first area may be reduced again. It should be noted that the above two-stage dimming scheme is only an example of the multi-stage dimming scheme in the present embodiment, and the multi-stage dimming scheme based on the above principle all belongs to the protection scope of the present disclosure.

In some examples, the area of the first region in this embodiment becomes smaller as the distance between the human body position and the smart interactive tablet becomes smaller. It is easy to understand that, when the user operates in a close range, the smaller first area can be set, so that the user can operate the first area, and meanwhile, the user who watches in a long range can see more contents except the first area, and the watching experience is improved.

In some examples, the processor of the smart interaction tablet of the present embodiment is further configured to perform:

receiving a touch operation instruction of the first area; and converting the touch operation instruction of the first area into a touch operation instruction for controlling the second area. In implementation, a user can control the second area to perform the touch operation while performing the touch operation in the first area, that is, the touch operation command executed in the first area can be synchronously executed in the second area.

In some examples, in order to ensure that the user who is watching from a distance can watch the operation content of the user who is operating the smart interaction tablet, the present embodiment further provides a display manner of the second region, including but not limited to any one of the following:

mode 1) copying at least part of the content of the display area to the second area for display;

the embodiment can copy at least part of the content of the display area to the second area for display, so that the user can operate in the first area and can watch the content of the display area from a long distance without being influenced.

Mode 2) at least partial content of the first area is copied to the second area for display.

In this embodiment, the second region can be controlled to copy the content that is currently being operated in the first region, for example, the first region receives a click operation instruction to perform a click operation on an icon, and the icon and the click operation on the icon can be copied and displayed in the second region, or the first region receives a writing instruction to perform a writing operation, and the writing instruction and the writing operation can be copied and displayed in the second region, that is, the content displayed in the first region can be copied in the second region, and a corresponding operation is performed in the second region according to the touch operation instruction to the first region, so that a user who watches remotely can view the real-time operation content of the user who operates the intelligent interactive tablet in real time.

In some examples, after copying at least part of the content of the first area to the second area for display, the embodiment may further determine whether the writing instruction of the first area has been completed, and if it is determined that the writing instruction of the first area has been completed, remove all the content in the second area. After the user finishes writing, the remote user does not need to continuously watch the written content, so that all the content in the second area can be removed after the writing of the first area is finished, and the use experience of the remote watching user is improved.

In some examples, the display brightness of the second area may also be set to be greater than the display brightness of other areas in the display area. The second region is used for providing the remote watching user with watching, so that the display brightness of the second region can be set to be the highest brightness in the display region, and the use experience of the remote watching user is guaranteed.

In some examples, the luminance of the display region in this embodiment may be set to a plurality of different luminances, where the display luminance of the first region is the lowest luminance and the display luminance of the second region is the highest luminance, and if there are other regions in the display region besides the first region and the second region, the display luminance of the other regions is greater than the display luminance of the first region and less than the display luminance of the second region. Optionally, the display area further includes a third area, the display brightness of the second area is greater than the display brightness of the third area, and the display brightness of the third area is greater than the display brightness of the first area.

In some examples, the embodiment further provides a method for reducing full-screen display brightness, before determining the first area and the second area of the display screen, the method is further configured to receive a control instruction, reduce the full-screen display brightness of the display screen, where the brightness of the first area and the brightness of the second area are both reduced to be minimum, and if a touch operation instruction of the first area is received, increase the display brightness of the second area, so as to achieve an effect of controlling the display brightness of the first area to be lower than the display brightness of the second area.

In some examples, the present embodiment provides a display brightness recovery method, and a core idea is to adjust the display brightness of the first region after the first region is displayed at the display brightness for a preset time period after the display brightness of the first region is controlled to be lower than the display brightness of the second region, where the specific adjustment method includes, but is not limited to, any one of the following ways, specifically as follows:

mode 1) adjusting the display brightness of the first area to preset brightness after determining that the operation of the first area is finished for a preset time period;

in implementation, the preset brightness is used for representing default brightness set by a user, namely brightness display is carried out according to the preset brightness after the computer is started.

Mode 2) after the operation of the first area is determined to end the preset time period, adjusting the display brightness of the first area to the display brightness of the last preset time period;

for example, the display luminance of the first region is controlled to be L0, the display luminance of the first region is controlled to be L1 after the display luminance of the first region is controlled to be lower than the display luminance of the second region, and the display luminance of the first region is adjusted to L0 after the first region is displayed for 10 minutes at L1.

Mode 3) after the operation of the first region is determined to end the preset time period, the display brightness of the first region is adjusted to be the same as that of the second region.

In some examples, the present embodiment determines the preset brightness by any one of the following:

the method comprises the steps of 1, receiving a user image shot by a camera, and determining the preset brightness according to the brightness requirement which is stored in advance and corresponds to the user image;

in the mode, the intelligent interactive panel is provided with the camera, and corresponding brightness requirements are set for different users in advance and stored through a face recognition algorithm, so that personalized brightness can be provided for different users when each user is detected.

In implementation, the intelligent interactive flat panel is also provided with a camera for shooting user images; the processor receives a user image shot by the camera, and determines preset brightness according to the brightness requirement corresponding to the user image. The brightness requirements of different user images are different, and a more personalized brightness setting method can be provided. In some examples, a face recognition algorithm may be used to store the display brightness set by a person for a user with a specific brightness requirement, as shown in fig. 7, and the specific implementation flow is as follows:

step 700, starting up the intelligent interactive panel for the first time after installation, and prompting to set the brightness;

step 701, receiving a brightness requirement of a first user;

the brightness requirement includes, but is not limited to, a specific brightness value, or a brightness adjustment method. The brightness adjusting method includes, but is not limited to, the brightness adjusting method provided in this embodiment, or the method of adjusting the brightness according to the ambient brightness measured by the light detection sensor.

Step 702, judging whether an instruction for performing global setting is received, if so, executing step 703, otherwise, executing step 704;

step 703, setting the brightness requirement as the brightness requirement corresponding to all users;

step 704, setting the brightness requirement as the brightness requirement corresponding to the first user.

In this embodiment, after the brightness requirements of a plurality of users are set in the above manner, the face recognition algorithm is used to perform face recognition on the user image by using the user image shot by the camera on the intelligent interactive tablet, and the brightness requirement of the user corresponding to the user image is determined according to the recognition result, so as to set the brightness of the intelligent interactive tablet.

Mode 2, responding to a setting instruction of a user on brightness, and determining the brightness corresponding to the setting instruction as the preset brightness;

and 3, receiving the ambient brightness measured by the light detection sensor, and determining the preset brightness according to the pre-stored brightness corresponding to the ambient brightness.

In some examples, the embodiment further provides a method for setting display brightness in an eye protection mode, which specifically includes receiving an eye protection instruction sent by a peripheral device that establishes communication connection with the intelligent interaction tablet before controlling the display brightness in the first area to be lower than the display brightness in the second area, and reducing the display brightness of the full screen of the display screen.

The display brightness of the intelligent interactive panel is adjusted in a self-adaptive manner based on the core idea that the brightness of the first area is controlled to be lower than that of the second area, so that a user who operates in a close range can perform more comfortable operation experience while the viewing experience of a user who watches in a long range is not influenced.

Embodiment 1 and the positional relationship of the display area 800, the first area 801, and the second area 802 in this embodiment are shown in fig. 8, in which the combination of the first area 801 and the second area 802 forms the display area 800. As shown in fig. 9, a specific implementation flow of the first brightness adjusting method provided in this embodiment is as follows:

step 900, receiving a touch operation instruction of a user to a first area;

in an implementation, the touch operation instruction may be a click of a shortcut button provided on a stylus pen, an icon click operation on a touch screen, or a touch gesture for determining the first area.

The content displayed in the first area includes at least part of the content in the display area, for example, the first area copies the whole content of the display area or at least key elements, wherein the key elements include but are not limited to program icons, tool icons of a certain program, and handwriting pen icons of handwriting software. In the specific implementation, the content displayed in the display area is translated to the first area for display by zooming, or only key content is displayed, for example, a background image of the display area is omitted, and only key program icons or tool icons are displayed.

Step 901, determining a corresponding first area according to the touch operation instruction;

step 902, determining the second area as the remaining area of the display area except the first area;

and step 903, controlling the display brightness of the first area to be lower than that of the second area.

In an implementation, the operation of the user in the first area may be mapped to a full screen, for example, the user performs a text handwriting operation in the first area, the handwritten text is displayed in the first area and the second area simultaneously, and the text displayed in the second area is displayed by enlarging the text displayed in the first area in equal proportion.

In the embodiment, brightness adjustment and interactive control of the large-size display screen are combined, full-screen interaction of the current 135-inch display screen is difficult, and the current 135-inch display screen is large in size, so that operation or handwriting can be performed through the first area, and an operation instruction or handwritten handwriting can be displayed on the second area.

In some examples, a brightness adjustment option may also be displayed in the first region to provide brightness adjustment settings for close-up operation users. If the handwriting interface is currently located in the first area, the handwriting background of the first area can be directly set to be a low-brightness background or a brightness adjusting option is provided in the first area. If the first area is an operation interface, for example, a homepage, the homepage background can be removed from the first area in addition to displaying the operation icons, and the operation icons can be adjusted in size and reduced.

The positional relationship of the display region 1000, the first region 1001, and the second region 1002 in embodiment mode 2 and this embodiment is shown in fig. 10, in which the combination of the first region 1001 and the second region 1002 forms the display region 1000. As shown in fig. 11, a specific implementation flow of the second brightness adjustment method provided in this embodiment is as follows:

step 1100, receiving a touch operation instruction of a user to a first area;

step 1101, determining a corresponding first area according to the touch operation instruction;

step 1102, determining a corresponding second area according to the first area;

step 1103, setting the display brightness of the first area to be the lowest brightness, and setting the display brightness of the second area to be the highest brightness.

In implementation, the second area is used for copying the content of the first area, that is, the user's operation or writing in the first area can be copied in the second area. The second area may have a certain content overlap with other areas, i.e. the second area is floating on the upper layer of the display area.

Specifically, 3 areas can be formed on the full screen, a first area 1001 is a low-brightness area, and a user operates in the area; the second area 1002 is a high-brightness area, and the content completely copies the content of the first area 1001, that is, the content written by the user in the first area 1001 is synchronously displayed in the second area 1002; the remaining region 1003 other than the first region 1001 and the second region 1002 may adopt an intermediate luminance.

In some examples, after the user has finished writing, the contents of the second area 1002 disappear, leaving only the first area 1001. An animation effect may be set in an implementation, such as the second region 1002 floating towards the first region 1001 until the two regions merge into one.

In some examples, the display content of the remaining region 1003 may be scaled or panned, ensuring that the first region 1001 does not occlude already existing display elements.

And step 1202, controlling the display brightness of the first area to be lower than that of the second area according to a preset brightness level corresponding to the distance.

In some examples, controlling the display brightness of the first region of the smart interaction tablet decreases as the distance becomes smaller.

In this embodiment, a plurality of brightness levels are preset, so that the brightness of the intelligent interactive tablet can be adjusted according to the brightness levels, in an implementation, the higher the brightness level is, the higher the corresponding brightness is, or the lower the brightness level is, the higher the corresponding brightness is, and this embodiment does not limit the correspondence between the brightness levels and the brightness too much.

The brightness level in the embodiment corresponds to the distance from a human body to the intelligent interactive panel, and as the distance becomes smaller, the brightness level of the first area is reduced, and the display brightness of the corresponding first area is reduced; in some examples, as the distance becomes smaller, the luminance level of the second region increases, and the display luminance of the corresponding second region increases. In some examples, as the distance becomes smaller, the display luminance of the first region decreases while the display luminance of the second region increases.

In some examples, the brightness level in this embodiment corresponds to a distance interval to which a distance from a human body to the smart interactive tablet corresponds, and the display brightness of the first region is controlled to be lower than the brightness of the second region according to the brightness level corresponding to the distance interval to which the distance belongs, and in some embodiments, based on the above core idea, this embodiment provides a specifically implemented three-level dimming scheme, which specifically includes the following dimming schemes:

scheme 12a, if the distance is not less than the viewing threshold, controlling the display brightness of the first area to be the same as that of the second area;

optionally, the display brightness of the first area and the second area is controlled to be preset brightness; the viewing threshold set in this embodiment is used to represent that the distance from the human body to the intelligent interactive tablet is long, and is suitable for viewing the corresponding brightness value in long distance. Optionally, if the distance from the human body to the intelligent interaction panel is a long distance, the brightness of the intelligent interaction panel can be adjusted to a preset brightness. The preset brightness may be a brightness preset by a user, or a brightness corresponding to the current environment and obtained by automatic adjustment of a light detection sensor in the prior art. The above method in this example has been described for various embodiments of determining the preset brightness, and will not be described herein.

wherein the primary brightness is lower than the preset brightness; namely, the brightness of the intelligent interactive flat plate is controlled to be lower than that of the second area;

and 12c, if the distance is not greater than the operation threshold, controlling the display brightness of the first area to be the secondary brightness, and controlling the display brightness of the second area to be the preset brightness.

Wherein the secondary brightness is lower than the primary brightness.

According to the embodiment, whether a human body approaches the intelligent interaction panel or not can be detected in real time according to the proximity sensor or the distance sensor which is arranged in or outside the intelligent interaction panel, and the received instruction is fed back to the driving circuit of the intelligent interaction panel in real time. When a person approaches the front face of the intelligent interaction panel, the judgment is carried out according to the received feedback of the proximity sensor, when the linear distance S between the person and the intelligent interaction panel is S2< S < S1, the fact that the current user has a close-range use requirement can be set, the display brightness of the first area is reduced to L1 through the driving circuit, the display brightness of the second area is set to be L0, wherein L0 is preset brightness, and L1< L0. When the linear distance S between the human and the intelligent interaction panel is S < = S2, and it is determined that the current user has writing requirements, the display brightness of the first area is reduced to L2 through the driving circuit, and the display brightness of the second area is set to L0, wherein L2< L1.

In some examples, after controlling the display brightness of the first region to display for a preset period of time, the present embodiment readjusts the display brightness of the first region according to the display brightness corresponding to the distance. For example, in this embodiment, after a preset period of time is displayed according to the display brightness of the first region, and it is determined that the current distance S > = S1 from the human body to the smart interactive tablet, the brightness of the first region is restored to L0.

In summary, the adjusting method for adjusting the intelligent interactive tablet provided by this embodiment can effectively control the display brightness of the region operated by the user of the intelligent interactive tablet to be lower than the display brightness of other regions, and provide various ways for determining the first region and the second region and various ways for controlling the display brightness, so that the user experience of the user is improved when the user uses the intelligent interactive tablet in a close range, and the viewing experience of the user watching in a long range is not affected.
